CURVED TOUCH DISPLAY DEVICE

摘要

The present invention relates to a curved touch display device including: a display unit including a curved surface which is curved in a horizontal direction; a plurality of vertical transmitters which are located on a left end portion and a right end portion of the display unit in parallel with each other in a vertical direction and output injection signals to the center of the display unit in a horizontal direction; a plurality of vertical receivers which are located on the left end portion and the right end portion of the display unit in parallel with each other in the vertical direction and sense intensity of reflected signals generated as the injection signals are reflected by an object located on the surface of the display unit; and a control unit which calculates a vertical axis coordinate of the object located on the surface of the display unit by analyzing the signals received by the vertical receivers. A recognition error, generated when a capacitive method is applied to a curved surface, can be eliminated by forming a touch sensor by using a light sensor instead of the capacitive method.
